/**
 * This is the default exception handler for flows and services. The handler logs errors 
 * and will forward the message and exception to an exception endpoint if one is set 
 * on this Exception strategy.  If an endpoint is configured via the  
 * element, a Dead Letter Queue pattern is assumed and so the transaction will commit.
 * Otherwise, the transaction will rollback, possibly causing the source message to be 
 * redelivered (depends on the transport).
